上一篇中，我们启动了网络，接下来，我们使用mount到cli中的文件来创建和加入channel。
# 进入cli容器 docker exec -it cli bash # 在cli容器中使用mount进来的channel.tx文件和channel名称，来创建channel export CHANNEL_NAME=mychannel peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem 2017-12-27 07:58:17.084 UTC [msp] GetLocalMSP -> DEBU 001 Returning existing local MSP 2017-12-27 07:58:17.084 UTC [msp] GetDefaultSigningIdentity -> DEBU 002 Obtaining default signing identity 2017-12-27 07:58:17.219 UTC [channelCmd] InitCmdFactory -> INFO 003 Endorser and orderer connections initialized 2017-12-27 07:58:17.221 UTC [msp] GetLocalMSP -> DEBU 004 Returning existing local MSP 2017-12-27 07:58:17.221 UTC [msp] GetDefaultSigningIdentity -> DEBU 005 Obtaining default signing identity 2017-12-27 07:58:17.221 UTC [msp] GetLocalMSP -> DEBU 006 Returning existing local MSP 2017-12-27 07:58:17.221 UTC [msp] GetDefaultSigningIdentity -> DEBU 007 Obtaining default signing identity 2017-12-27 07:58:17.221 UTC [msp/identity] Sign -> DEBU 008 Sign: plaintext: 0AA2060A074F7267314D53501296062D...53616D706C65436F6E736F727469756D 2017-12-27 07:58:17.221 UTC [msp/identity] Sign -> DEBU 009 Sign: digest: 7E950EFF2E61E133D3AB78D889F9797342517D44A520F734999DEB31557AA8C9 2017-12-27 07:58:17.221 UTC [msp] GetLocalMSP -> DEBU 00a Returning existing local MSP 2017-12-27 07:58:17.221 UTC [msp] GetDefaultSigningIdentity -> DEBU 00b Obtaining default signing identity 2017-12-27 07:58:17.221 UTC [msp] GetLocalMSP -> DEBU 00c Returning existing local MSP 2017-12-27 07:58:17.221 UTC [msp] GetDefaultSigningIdentity -> DEBU 00d Obtaining default signing identity 2017-12-27 07:58:17.221 UTC [msp/identity] Sign -> DEBU 00e Sign: plaintext: 0AD9060A1508021A060899A58DD20522...A21B132E4F8F67D731A56F663068862D 2017-12-27 07:58:17.221 UTC [msp/identity] Sign -> DEBU 00f Sign: digest: E7B4F70C95537A5C12A37C25E590AAD3F526374542992264C087342F74AF7CD8 2017-12-27 07:58:17.387 UTC [msp] GetLocalMSP -> DEBU 010 Returning existing local MSP 2017-12-27 07:58:17.387 UTC [msp] GetDefaultSigningIdentity -> DEBU 011 Obtaining default signing identity 2017-12-27 07:58:17.403 UTC [msp] GetLocalMSP -> DEBU 012 Returning existing local MSP 2017-12-27 07:58:17.403 UTC [msp] GetDefaultSigningIdentity -> DEBU 013 Obtaining default signing identity 2017-12-27 07:58:17.403 UTC [msp/identity] Sign -> DEBU 014 Sign: plaintext: 0AD9060A1508021A060899A58DD20522...2CC696F9B87D12080A021A0012021A00 2017-12-27 07:58:17.403 UTC [msp/identity] Sign -> DEBU 015 Sign: digest: A4C9FE61C16D70247F13AFCDE9414896600B96932D44FFB92A6FD71F07705013 2017-12-27 07:58:17.429 UTC [channelCmd] readBlock -> DEBU 016 Got status: &{NOT_FOUND} 2017-12-27 07:58:17.430 UTC [msp] GetLocalMSP -> DEBU 017 Returning existing local MSP 2017-12-27 07:58:17.430 UTC [msp] GetDefaultSigningIdentity -> DEBU 018 Obtaining default signing identity 2017-12-27 07:58:17.440 UTC [channelCmd] InitCmdFactory -> INFO 019 Endorser and orderer connections initialized 2017-12-27 07:58:17.641 UTC [msp] GetLocalMSP -> DEBU 01a Returning existing local MSP 2017-12-27 07:58:17.641 UTC [msp] GetDefaultSigningIdentity -> DEBU 01b Obtaining default signing identity 2017-12-27 07:58:17.641 UTC [msp] GetLocalMSP -> DEBU 01c Returning existing local MSP 2017-12-27 07:58:17.641 UTC [msp] GetDefaultSigningIdentity -> DEBU 01d Obtaining default signing identity 2017-12-27 07:58:17.641 UTC [msp/identity] Sign -> DEBU 01e Sign: plaintext: 0AD9060A1508021A060899A58DD20522...E73F6E4CC50612080A021A0012021A00 2017-12-27 07:58:17.641 UTC [msp/identity] Sign -> DEBU 01f Sign: digest: 3C9624452A8991FE45E1EE1424522D30569EB92FFD891787A30F146DA586B89F 2017-12-27 07:58:17.644 UTC [channelCmd] readBlock -> DEBU 020 Received block: 0 2017-12-27 07:58:17.644 UTC [main] main -> INFO 021 Exiting..... ls . channel-artifacts crypto mychannel.block scripts
-c 指定了channel名称；
-f 指定了channel配置文件（channel.tx-configtxgen创建）；
这个命令返回一个genesis block -
